Steve thinks he can drive legally 30 minutes after he drinks 5 beers. the legal limit is bac = 0.08. give a 90% prediction interval for steve’s bac. can he be confident he won’t be arrested if he drives and is stopped? hint: a level c confidence interval for the mean response (my) is given by the following equation: [my-hat + t*se, my-hat + t*se], where se is the standard error for the estimate of the mean response.
